Tab controls allow you to easily create multi-page forms. Create
a tab control by following these steps:

Click the Tab Control icon on the toolbox and draw the
control on the form.

Add new controls to each tab page the same way that controls
are added to regular form pages and click the tabs to change pages.
Existing form controls cannot be added to the tab page by dragging
and dropping. Instead, right-click on the control and select Cut
from the shortcut menu. Then right-click on the tab control and
select Paste. The controls can then be repositioned on
the tab control.

Add new tabs or delete tabs by right-clicking
in the tab area and choosing Insert Page or Delete
Page from the shortcut menu.

Reorder the tabs by right-clicking on the
tab control and selecting Page Order.

Rename tabs by double-clicking on a tab and
changing the Name property under the Other tab.

Conditional Formatting

Special formatting that depends on the control's value can be added
to text boxes, lists, and combo boxes. A default value can set along
with up to three conditional formats. To add conditional formatting
to a control element, follow these steps:

Select the control that the formatting should be applied to
and select Format|Conditional Formatting from the menu
bar.

Under Condition 1, select one of the following condition
types:

Field Value Is applies formatting based upon
the value of the control. Select a comparison type from the
second drop-down menu and enter a value in the final text
box.

Expression Is applies formatting if the expression
is true. Enter a value in the text box and the formatting
will be added if the value matches the expression.

Field Has Focus will apply the formatting
as soon as the field has focus.

Add additional conditions by clicking the Add >>
button and delete conditions by clicking Delete... and
checking the conditions to erase.

Password Text Fields

To modify a text box so each character appears as an asterisk as
the user types in the information, select the text field in Design
View and click Properties. Under the Data tab, click
in the Input Mask field and then click the button [...]
that appears. Choose "Password" from the list of input
masks and click Finish. Although the user will only see asterisks
for each character that is typed, the actual characters will be
saved in the database.

Change Control Type

If you decide the type of a control needs to be changed, this can
be done without deleting the existing control and creating a new
one although not every control type can be converted and those that
can have a limited number of types they can be converted to. To
change the control type, select the control on the form in Design
View and choose Format|Change To from the menu bar. Select
one of the control types that is not grayed out.

Multiple Primary Keys

To select two fields for the composite primary key, move the mouse
over the gray column next to the field names and note that it becomes
an arrow. Click the mouse, hold it down, and drag it over all fields
that should be primary keys and release the button. With the multiple
fields highlighted, click the primary key button.
